It works on w2k Advanced Server, Pro, Server, sp1/sp2, nt4/sp6, with and
without administration rights.
It works on gost w2k on vmware.
It doesn'n work on Whistler 64 bit Beta 1, XP Pro beta 1, XP pro RC1.
(Seems to they fixed this bug)
It doesn't attached to ping only.
Can it be some kind of bouffer overflow?

I've been able to make it work using both an administrator account and a
non-administrator account. (That is, a user account with administrator
privlleges, and one without.)

Windows 2K 5.00.2195
SP 2
Hotfixes current.

I've verified this to work on Win2K Pro SP2.  It took 3 F7s and my 
system hard-booted as if I had hit the reset button.

On a Win2K Server SP2 on a terminal session (administrator mode) it
doesn't
crash the box.  However:
 - You can create a "cmd.exe" session that is unkillable
 - You can't log off that session
 - You can't kill that session or "cmd.exe" process from the console
(taskmgr.exe)
 - You can't log the user off from Terminal Services Manager
 - You can't create another instance of "cmd.exe" in that terminal 
session
 - A reboot is required to kill the session.

Hello, this is a new bug found in W2K in all flavors, works with all
levels
of users.

Here is the proof of concept:

Open a Cmd Window
Ping to any host (for example ping 10.100.2.1 preferred a host in your
LAN),
no switch needed. Just ping
Now press F7 and Enter (try a couple of times quickly...less than ten 
,
and
you can see what a meaning)
The machine reboots, from nothing a warm reboot.
Please let me know if you have the same bug. I tried this in W2k sp2
English
and Spanish.
